  • The rate of heat release is probably the single most important measure of fire hazard. Several tech-niques were developed for the measurement of rate of heat release, but were not suitable for fire test-ing purpose. Recently the application of oxygen consumption principle made it possible to development of well-characterized heat release rate measurement apparatus, the furniture calorimeter for large-scale fire tests and the cone calorimeter for bench-scale fire tests. The cone calorimeter can be used to determine the ignitability as well as heat release rate and smoke development, mass loss rate, combustion gas production etc. from burning materials. Thus, test method using cone calorimeter, an internationally recognized and accepted for the evalua-tion of fire properties, is a very promising tool for combustion study on various kind of materials and products.

  • Wood-Plastic Composites (WPCs) are one of spotlighting materials for the residential construction and the industry for furniture. At this study, the limiting oxygen index (LOI) was measured by ASTM D 2863 and the cone calorimeter test was done by ISO 5660-1 to find the combustion characteristics of WPCs. In addition, the identical test was implemented to compare the combustion characteristics between the red pine and the antiseptic wood. The result of LOI measurement showed that the LOI of WPCs was lower than that of red pine or antiseptic wood. The cone calorimeter test showed that the heat release rate (HRR) of WPCs was the highest and the Peak HRR as well as the average HRR and total heat release of WPCs was higher than those of red pine or antiseptized wood

  • In this study, fire-retardant chemicals were melt with mixed composition ratios of dibasic ammonium phosphate and each half of boric acid and borax in hot water, in which hammer-milled chips were immersed to increase swelling of waste particleboards. Also, fire-retardant treated particles from sawn lumber chip and recycled particleboard chip were composed in ratio of 70:30 in core layer to improve boards' properties. Retention ratio of fire-retardant chemicals for the particles for face layer was high due to high specific surface area, and that of sawn lumber chips was somewhat higher than that of recycled particleboard chips. The mixture of particles from sawn lumber chips and recycled PB of 70:30 in weight ratio exceeded bending strength of 100 $kgf/cm^2$. It seemed that the relatively greater portions of dibasic ammonium phosphate affected adversely to dimensional stability, however fire-retardants treatment resulted in distinct effect lowering formaldehyde emission such as $E_0$ type(0.5mg/$\ell$ or less) in KS F 3104. In fire-retardancy, the recycled boards with a mixed ratio of dibasic ammonium phosphate to boric acid borax(50:50 mixture) of 70% to 30% in weight satisfied fire-retardancy 3rd grade in KS F 2271, and also this composition from cone calorimeter test met same standard grade figuring total heat release of 4.6MJ/$m^2$.

  • In the case of residential facilities, general fire scenarios cannot be applied. Becauseit is difficult to quantify due to the types of combustibles and various fire loads. Existing research conducting surveys of combustibles, but research on fire characteristics is insufficient. Therefore, in this study, an Excel macro that can be quantified by experimenting with the HRR experiments of sofa, drawer, mattress, chair, desk and TV, which are typical combustibles. As a result of experimenting 6 loading combustibles in domestic residential facilities by using a furniture calorimeter, values of 2,391.26kW appeared from the sofa, 1,891.80kW from the drawer, 1,778.95kW from the mattress, 1,104kW from the chair, 291kW from the desk, and 135.09kW from the TV. Also, by applying the α value of the fire growth rate by classifying fire-growing speeds at NFPA 72 (National Fire Alarm Code 2007, Annex B), the mattress can be defined as Very Fast, the sofa and drawer Fast, the TV Slow, the desk Slow, and the chair Medium.

  • 최근 건축물에서 공동주택의 비율이 증가하고 있으며 동시에 공동주택의 화재비율도 증가하는 경향을 보이고 있다. 또한 화재 시 인명 피해의 주원인인 가연물은 소재가 다양화되고 있으나 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 따라서 본 연구는 전보의 실내장식물에 이어 공동주택에서 많이 사용되어지는 적재가연물을 가연물 조사를 바탕으로 선정하여 Furniture Calorimeter를 이용해 그 연소특성을 알아보았다. 그 결과, 소파가 타 시료에 비해 화재 시 높은 위험성을 나타냈으며, 일본건축학회에 발표된 데이터와 비교한 결과 소파의 데이터가 유사한 것으로 나타났다.

  • 본 연구에서는 다세대 주택에서 발생되는 화재에서 가연물질이 되는 가구류에 대한 화재 특성을 파악하기 위해 단위 가연물에 대한 열방출율(HRR, Heat Release Rate), 연기발생량, 유독가스 발생량 등에 대한 기본 DB를 확보하고자 하였다. 실험에 사용된 단위가연 물에는 침대(매트리스 포함), 장롱, 화장대, 책상, 책장, 소파(3+1인용), TV, 싱크대(찬장포함), 냉장고, 이불(옷가지)등 총 12여종이며, 국제 시험 규격인 ISO 9705 시험법인 중규모 시험 장치(Room Corner Tester)와 10MW 급의 실규모화재실험장치(Large Scale Calorimeter)에서 실험을 진행하였다. 실험결과 냉장고에서 가장 높은 최대 열방출율 약 3051 kW, 장롱에서의 일산화탄소 방출량은 최대 약 3894.2 ppm, 이산화탄소의 방출량은 최대 약 1.8% 로 가장 높게 측정되었다. 이러한 중규모 시험 장치를 통한 단위 품목의 화재특성 DB 작성은 단위구획에서의 화재 확산 예측에 가장 중요한 요소가 될 수 있을 것이다.
